Schloss Kroisbach, building in Styria, Austria

Schloss Kroisbach, also called Haignitzhof, is a castle in the Mariatrost area of Graz situated on a western slope. The building has a rectangular shape with two floors, two interior courtyards, and a small wooden tower with a bulb-shaped roof on one side.

The castle was built between 1650 and 1655 in the Baroque style by Domenico Rossi for Count Abundio Inzaghi. In the 19th century it was renovated by the Galler family, and in 1965 the west facade underwent restoration.

The name Haignitzhof recalls the estate's older designation, while Kroisbach links it to the stream below the western slope of the Grazer Platte. The building sits in the Mariagrüntal valley in Mariatrost, Graz's eleventh district, where the grounds and surrounding gardens are still worked.

Schloss Kroisbach stands on the western slope of the Grazer Platte in the Mariagrüntal valley, in Graz's 11th district, Mariatrost. The sources record no opening times or visitor access, so check locally before setting out. The west facade was restored in 1965; the round-arch stone portal and the two inner courtyards are on the building itself.

Inside the castle there are special stoves from the Biedermeier period found in a small corner room on the southeast side. These preserved stoves are a rare witness to domestic life from that era and show how people heated and lived at that time.
